WALL-PAPER- TRIM M l N-G MACHINE.

ySPECIFICATION forming'V part of Letters Patent No. 254,443, dated February 28, 1882.

A Application tiled June 11, 1881. (No model.)

' To alt whom it may concern -two longitudinal guides which are parallel to each other, through which the paper is drawn by means of a revolving shaft, as it is cut or trimmed the desired width by means of circular knives on the ends of a revolving shaft at the opposite end of the machine to the end containing the draft-roller above mentioned. Between the two shafts any desirable number of rollers are arranged in arch form for the sup- The rollers and the shafts are so connected with one ofthe above-mentioned guides as to be prevented from shifting longitudinally, while they have a rotary movement; butin order to adjust the other guide any desired distance from its fellow to suit the desired width for trimming the paper the two shafts and the series of rollers connected therewith at their ends have a shifting movement, as hereinafter fully described. 'lhe above-mentioned guides have at their ends with which the Vcutter-shaft is connected circular bearings to contain the roll of paper to be cut or trimmed, and a rest-bar for the paper between these bearings and the cutters, the bar having a fixed connection with the stationary guide at one end and a sliding connection at its other end with the adjustable guide.

As the construction and arrangement of the several parts of the machine are full v described in the body of the specification, a specific description is omittedin this place.

In the accompanying drawings, which make a part of this specification, Figure l is a plan view of my improved wallpaper-trimming machine. Fg. 2 is a side elevation of the same.

Fig. 3 is a side view of the revolving cuttershaft B', provided with cutters G and G' and a grooved pulley, E'. Fig.4is a side view, on an enlarged scale, of the adjustable hub d? of the shaft B. Fig. 5 is aface view of a washer, h, on an enlarged scale. Fig. is a plan view, on an enlarged scale, of an end portion ot' the cutter-shaft B', providedvwith a circular cutter, G', and the stationary cutter H, connected therewith. Fig. 7 is a portion, on an enlarged scale, ofthe adjustable guide C', having a re'- cess, t', for the reception of the washer h. Fig. 8 is a side elevation ofthe adjustable guide C', in connection with the bed-plate A, which is shown in longitudinal section. lFig.9 is a crosssecton ofthe shaft B on an enlarged scale.'

Like letters of reference in all the figures indicate Ithe same parts.

A represents the bed-plate of my improved machine.

B is a revolving shaft, on which the paper is wound as it is trimmed by revolving knives on the shaft B' and stationary knives combined therewith, as hereinafter described.

O and O' are parallel guides for the paper as it is drawn forward and wound on the abovementioned shaft B. These guides have pedestals or legs a, in which are suitable bearings for the journals of the shafts B and B', the legs being provided with feet b, which rest in the grooves c c of the bed-plate A, and are secured in their places by means of bolts. The guide C' is adjustable in adaptation to the various widths the paper is required to be trimmed, the feet of the guide being moved along in thc grooves c c ofthe bed-plate in the adjustment. There is a series of rollers, D, arranged in arch form between the shafts B and B', for the support of the paper, whereby the sagging ofthe paper is prevented as it is drawn forward and wound on the shaft B. The rollers turn in suitable bearings in the guides O and C'. The shafts B and B' are provided respectively with the pulleys E and E', which are connected together by means of the band F, to provide for the cutter-shaft B' being revolved by the shaft B, when the latter is driven by any suitable means, for the purpose of revolving the circular cutters Gr and Gr' on the guide C' to suit the width the paper is to be` cut or trimmed, the hubs being made fast in their adjusted position by means of the set screws g. The journal part of these hubs d2 and d3 also has bearings in the guide C and additional bearings in the arms f' f', Which arecast fast to the guide C'. There are washers h placed on the journals of the hubs d and d2, against the shoulders of the journal, which tit recesses i of the guides C and C. At the other end of the guides are similar recesses, in which the cutters G andG' are permitted to revolve, so as to bring the cutters in line with the guides.

H H are stationary cutters, against which .the circular cutters G and G work. One of them is shown on an enlarged scale in Fig. 6, in connection With a cutter, G'.

The ends ofthe rollers D, in connection with the stationary guide C, are provided with a shoulder, and have a washer and nut, so as to bring the guide between the shoulders and Washers in such a manner as will admit of the rotary movement of the rollers, but prevent their shifting in the direction of their -lar direction of the rollers.

length. There is a rod, J, inside of the cuttershaft B for guiding the paper after it passes t the cutters, to make it bindv on the first supporting-roller D, and thereby take the circli- This rod has a fixed connection in its longitudinal position with the stationary' guide C, but ts loosely in the guide C', in the manner of thev rollers. D. Between the cutter-shaft B and thc bearings jj at this end of the guides, in which the ends of a roll of paper to be trimmed are laid,y there is a guiding-bar, l, for the paper as it passes t0 the cutters. This bar has one endpermanently connected with the stationary guide O,

- but the other end its loosely7 in the opening or slot 7c of the adjustable guide U'.v

The operation of the machine is as follows:

A roll of paper to be trimmed is placed in connectionwith the circular bearingsjj, and the ycircular knives'or cutters G and G' being rotated by means of the connection f their shaft B with thedriving-shatt B, as above described, the outer end of the paper is drawn forward by hand, for the trimming ofits edges, far enough to connect the end of the paper with the 1ongitudinal groove l of the shaft B. Then by turning the shaft partly around the paper is connected fast therewith, and by continuing the revolution of the shaft the Whole roll is drawn forward and trimmed at both edges at one operation, being wound in its forward movement on the shaft B. When the trimming is completed this shaft is drawn out of vthe trimmed roll, said roll removed and the shaft re-engaged With the machine, and the like operation gone through with another untrimmed roll of paper, and so on continuously.

vBy having vthe knives H 'H fastened to the guides Gand C', and the Vlatter also provided with the circular rests for the roll of untrimmed paper, the position ot' the said knives or cutters H H and rests jj in relation to the revolving cutters Gand G is not disturbed in any manner in changing the machine to trim the paper to various Widths, each Change being effected by simply adjusting the guide C' and cutter G'.

I claim as my inventionl. In a Wall-paper-trimming machine, in combination with the revolving shaft B, having a stationary knife, G, and an adjustable knife, G', the stationary guide C and adjustable guideG', having each a knife, H, and paper-roll restj, whereby to adapt the trimmingmachine to trim the paper to any desired Width by simply adjusting the guide G' and 'the revolving knife or cutter G', substantially as described. l

2. The combination ofthe series of supporting-rollers D, arranged in arch form, with the revolving. cutter-shaft B', the guides C and C', and the winding-shaft B, having a longitudinal groove, Z, substantially as and for the pur- -pose set forth.

3. The-combination of the revolving shaft IB, having a pulley, E, provided with a hub, d, at

one end, and a hub, d2, at its other end,with the guides C and C', having arms f and f respectively, and with the cutter-shaft B', having a pulley, E', provided with a hub, el', at one end,

and a hub, d3, at its other end, the hubs d2 and d3 being adjustable, substantially as described.
